World of Warcraft's Patch 11.1 will automatically convert leftover Bronze Celebration Tokens into Timewarped Badges. This conversion, at a rate of 1 Bronze Celebration Token to 20 Timewarped Badges, will occur upon players' first login after the patch launches.
The WoW 20th-anniversary event, concluding after 11 weeks, allowed players to accumulate Bronze Celebration Tokens used for purchasing revamped Tier 2 sets and anniversary collectibles. Any remaining tokens could previously be exchanged for Timewarped Badges, the currency for Timewalking events.
Blizzard confirmed that Bronze Celebration Tokens will not be used again, prompting this automatic conversion to prevent players from having unusable currency. This conversion will happen automatically upon logging in after Patch 11.1's release.
While a release date for Patch 11.1 is unannounced, considering the timing of in-game events (Plunderstorm and Turbulent Timeways), February 25th is a strong possibility. This means the conversion will likely occur after the current Turbulent Timeways event concludes.
Timewarped Badges, obtained through this conversion, can be used in future Timewalking events, ensuring players aren't left with wasted currency. The rewards purchasable with Timewarped Badges will remain available.
